The Long-Term Evolution (LTE) is often called “4G”, but many also claim that LTE release 10, also known to as LTE-Advanced, is the true 4G evolution step, with the first release of LTE ( Release 8 ) then being labeled as “3.9G”.

This ongoing race of increasing sequence numbers of mobile system generations is in fact just a matter of labels. What is essential is the actual system capabilities and how they have advanced.

The evolution of 3G systems into 4G is powered by the creation and growth of new services for mobile devices, and is enabled by advancement of the technology available for mobile systems.

IP Multimedia Subsystem (IMS) Emergency Sessions - Part 1

0

Non Voice Emergency Service (NOVES ) allows the UE to use other media and communication types other than voice and GTT during an IMS emergency session when the network supports IMS emergency service and the UE also supports other media or communication types.

In case of Emergency session over IMS, Emergency sessions should be prioritized over non-emergency sessions by the system.

Minimization of drive test coverage optimization

In this part the main focus on different use cases where MDT can be applied.

Minimization of Drive Test (MDT) specifies different ways to improve network efficiency by using UE measurement logs. The logs collection in UE can be periodic or event triggered (e.g Radio Link Failures).

To make the MDT process more efficient and provide adequate results, different use cases are defined.

Minimization of drive test

1

Wireless network is one of the most complex system and to make sure that the Network is working as per the standards and serving the users optimally, the telecom operators perform drive tests. These tests are carried out for different reasons, some times to optimize the network and some other times to debug certain issues in a particular area. The (more ..)

Rohde & Schwarz Tests VoLTE and Audio Quality

0

Rohde&Schwarz demonstrated voice over LTE (VoLTE) and audio quality measurements with the R&S®CMW500 wideband communication tester and the R&S®UPV audio analyzer at LTE North America 2011. For the demonstration a commercial LTE USB dongle in collaboration with an IMS client running on a PC was used to simulate a VoLTE-capable device. This setup registered to an IMS server via LTE (more ..)
